What is formed when water Vapour comes in contact with very cold air *?

Answer: Evaporation takes place from all open surfaces of water. At sufficient heights, the air becomes so cool that the water vapour present in it, condenses to form tiny drops of water called droplets. It is these tiny droplets that remain floating in air and appear to us as clouds.

What happens when water Vapour comes in contact with a cold bottle of soda Why is it so?

When water vapor in the air comes into contact with something cool, such as the outside of a cold glass of lemonade, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That’s condensation!

What is the process of converting water into water Vapour?

Solution: (a) The process of changing water into its vapor state is called evaporation.

Which process is responsible for the formation of water Vapour?

Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.

When does water Vapour changes into water?

Condensation
Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.

What is meaning of water Vapour?

Definition of water vapor : water in a vaporous form especially when below boiling temperature and diffused (as in the atmosphere)

When does vapor turns into form of water or snow?

When does vapor turn into form of water or snow? Explanation: Water is evaporated from surface of earth and stored in form of clouds. When the vapors in the atmosphere are cooled below dew point temperature, it falls in the form of water or snow depending on the atmospheric temperature.

What is the process of making vapour from water?

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle.

Why is water vapour important?

Water vapor is the most important greenhouse gas. It controls the Earth’s temperature.” It’s true that water vapor is the largest contributor to the Earth’s greenhouse effect. On average, it probably accounts for about 60\% of the warming effect.

What are examples of water vapor?

An example of water vapor is the floating mist above a pot of boiling water. Water in the form of a gas; steam. Water in its gaseous state, especially in the atmosphere and at a temperature below the boiling point. Water vapor in the atmosphere serves as the raw material for cloud and rain formation.

What causes water Vapour?

What happens to water vapor when it cools down?

Water vapor molecules lose heat energy to the colder object. The water vapor molecules slow down and condense, forming water droplets or ice crystals on the cold object. Looking for free Rx coupons? Right this way.

Why is water vapour made up of water molecules?

Because water vapour is made up of water molecules which have been heated. These water molecules have extra energy in the form of heat. Remember water vapour is not a liquid but a gas or air. Hot air rises. Hence water vapour is really just hot air that contains some water molecules .

How does water change from gas to liquid phase?

Think of water molecules in the air as little tongues. As soon as they hit anything colder than they are, they stick. That is called condensation. When there are enough water molecules stuck in one pile, they form a droplet and that means they have gone from gas phase to liquid phase.

What happens when vapor pressure is less than ambient pressure?

When the vapor pressure is less than the ambient pressure, then the concentration (percent) of that vapor is directly proportional to the ratio of the vapor pressure of that liquid to the the total pressure.
